Hello all,

I am having problem in updating the code to STM32F103ZCT7 using ST link V2.

I am getting the error as ''Can not connect to divice; Internal Command Error''

I am using three pins SWDIO, SWCLK, NRST.

I have cross check the connections using multimeter & all are OK.

I have not connected AVcc & AVss pins as well as Vbat pins i.e. they are floating, can this create any problem?

Please suggest.

Thanking You all.

Analogue supplies are not optional, they control the Power-On-Reset circuit.
